Milous. What is the factory fill oil. Brand and type. Where all filled the same? I saw an update from Chrylser saying 0W-40 was correct and the 5W-40 was wrong.

i researched this issue, and turns out there is no different at all, 0w is used mostly for regions that snow alot ! and it reaches freezing point ( thats y its recommended back at the states ).
and in our case it is recommended by chryco to use 5w since our region is so hot, today it reached 43 celsius and trust me its boiling here, but still the wk2 managed it so fine.
any more concerns dont hesitate.
